Two genera are discussed; 3 species of Choristoneura are treated; Cacoecia heliaspis MEYRICK and C. occidentalis Walsingham are transferred to Choristoneura; C. freemani n. nov. is a replacement name for Nearctic C. occidentalis FREEMAN not WALSINGHAM. Of three species of Procrica two (P. marieskopa sp.n., P. pilgrima sp. n.) are newly described. KEY WORDS: Lepidoptera, Tortricidae, new species, Afrotropical. INTRODUCTION This paper is the sixth of the series on the Tortricidae of South Africa based primarily on the collection of the Transvaal Museum, Cape Town where the holotypes are deposited. Choristoneura and Procrica are treated as closely related (RAZOWSKI 2002a). There are some other genera close or synonymous with first of them and some require description. Three of them are listed by RAZOWSKI (1992) and one, Meridemis DIAKONOFF, 1976, is also found in this region. Abbreviations MNHL - Natural History Museum London Acknowledgements The author would like to express his gratitute to the authorities of the Transvaal Museum, especially to Dr. Martin KRÜGER the former curator of the Lepidoptera Department. Polish Journal of Entomology 77 (3) 246 Thanks are also due to Dr. º. PRZYBYºOWICZ who photographed the moths and Mr. K. FIOºEK, Cracow for arranging the plates. Choristoneura LEDERER, 1859 RAZOWSKI (1992) revised Choristoneura dealing with the Palaearctic and Nearctic species. He also mentioned that its species "do not penetrate the Oriental region but only approach the western and northern intermediate zone, if we accept Meridemis as a distinct genus" and that Choristoneura does not occur even in the northernmost parts of the Neotropical region. Recent studies allow us to suppose that this genus has some Oriental representatives, e.g. in Vietnam. RAZOWSKI (2002a) found it in the Afrotropical region describing one species from Cameroon. Now we are convinced that Choristoneura has more African representatives. Choristoneura occidentalis (WALSINGHAM, 1891), comb. n. Material examined Lectotype male: "Syntype; Gambia, Bathurst, XI - 1884 - 5, CARTER 1886, No. 88"; GS 4761 BM; paralectotype, female, similar label ("CARTER 1885, No. 278"); GS 4719 BM. Description Male genitalia (Figs 1, 2) as described for heliaspis but with longer terminal part of sacculus. Female genitalia (Fig. 11) also similar to heliaspis but with somewhat longer ductus bursae, smaller sclerite of antrum and seemingly larger signum. Remarks BROWN (2007) placed Cacoecia occidentalis in Archips HÜBNER, [1825] and sunk Cacoecia heliaspis as its synonymy. FREEMEN (1967) described from Washington, USA another species, Choristoneura occidentalis which becomes its younger homonymy (RAZOWSKI 1992). I am proposing for the latter a replacement name Choristoneura freemani. The ebove mentioned characters may prove insufficient for separation of heliaspis from occidentalis hence a wider material should be examined for variation or local forms. In the NHML there are numerous specimens from several African countries (from Sierra Leone to Zanzibar) with similar facies. RAZOWSKI J.: Tortricidae (Lepidoptera) from South Africa 247 Choristoneura heliaspis (MEYRICK, 1909), comb. n. (Figs 16 - 18) Description Male genitalia (Figs 3, 4). Uncus broad, rounded terminally; socius small; arm of gnathos weakly expanding subterminally, terminal plate very large; valva subsquare with rounded posterior corners; sacculus slender with small terminal process; transtilla narrowing medially; aedeagus slender posteriorly; coecum penis atrophied; cornuti up to three moderate spines. Female genitalia (Fig. 16). Sterigma rather short, with well developed lateral arms; sclerite of antrum short; ductus bursae with 7 or 8 coils; cestum long; signum small. Material examined Over 30 males and and 14 females from: South Africa: Port St. Johns (10-22.II.1955, A.T.J. JANSE; 20.I.1953, C.G.C. DICKSON); Durban (IV. 1954; 23-29.II.1952; II. 1955; III.1954; XII. 1954, etc., C.G.C. DICKSON;); Umdomi Park (11-16.V.1974, L. Va'ri); Ndumu, Natal (10-12.II.1968, POTGIETER & JONES); Bobomene (10.V.1974, POTGIETER & SCOBLE); St. Lucia Lane, N, (X. 1934, H.W. BELL MARLEY); Nelspruit, Stonehaven (31o11'E 25033'S, 1.II.1989, N.J. DUKE); Mtumatuba, Natal (E.R. HARRISON); Nelspruit, Tvl (28.I. 1981, M. SMIT); Nelspruit: Stonehaven. Mozambique: Moronga Forest, Moz.[ambique] (20o03'S 33o09'E, 6-11.IX.1972, R.H. JONES); Chiluvo, Moc.[ambique] (26.III.1963, D.M.C. Cookson); Xiluvo, VIIa Machado Distr. (9-10.III.1964, VARI & VAN SON). Remarks This species was described in the genus Cacoecia HÜBNER, [1825] and placed by BROWN (2005) under its older synonymy Archips HÜBNER, [1825] as a synonymy of C. occidentalis to which it is similar externally and shows analogous variation (Figs 16-20). C. heliaspis characterizes with small terminal part of sacculus. Choristoneura psoricodes (MEYRICK, 1911) (Fig. 19) Description Male. Wing span 19.5 mm. Head and thorax ochreous cream, labial palpus (ca 3) and tegula mixed with brownish. Forewing slightly expanding terminally; costa weakly curved at base, without fold; apex broadly rounded; termen somewhat oblique, almost straight. Ground colour cream slightly suffused and densely strigulated with yellow-brown; in ter- Polish Journal of Entomology 77 (3) 248 minal part of wing some veins similarly suffuded. Marking yellowish brown in form of incomplete fascia extending from mid-costa towards tornus where ill-defined, small subapical blotch. Cilia cream scaled with yellow ochreous, browner at apex, cream at tornus. Hindwing brownish cream, darker on peripheries than at base, with indistinct brownish grey strigulation; cilia whitish. Female. Wingspan 21-23 mm; labial palpus ca 4. Strigulation of forewing darker than in male; hindwing brownish grey. Variation. Ground colour of forewing and strigulation more or less dark; some dots and basal line of cilia darker, rust brown. Male genitalia (Fig. 13, not known until now). Sterigma with large, folded lateral parts and strong cup-shaped part fused with the sclerite of antrum; its more proximal portion forms a broad colliculum; ductus bursae rather short, with cestum; signum with atrophied basal plate, with moderate blade and slender capitulum. Material examined Eight specimens from Jonkershoek (22-23. X. 1965, L. VARI); Graskop, Tlv. (4. IX. 1954, G. VAN SON); De Hoop, Cape Prov., Bredasdorp Distr. (1-3.XI. 1967, VARI & POTGIETER). Remarks This species was described from South Africa (Haenertsburg and Woodbush Village, Transvaal). CLARKE (1958) illustrated the male lectotype preserving its original position in Tortrix auct. BROWN (2005) placed it in Epichoristodes DIAKONOFF, 1960. The examined specimens exactly fit the description and the illustration of the moth. There are some small differences in the sacculus and aedeagus only (compare Figs 5, 6). I am including psoricodes in Choristoneura mainly on basis of similarity in the shapes of uncus, transtilla and valva. The males of examined examples are without costal fold. Procrica DIAKONOFF, 1960 Remarks Since description of this genus (DIAKONOFF 1960) new taxa have been successively added (cf. RAZOWSKI 2002b, nine species included). Now further two species are placed in this genus. The present additions confirmed the characteristics of the genus and its similarity to Choristoneura. The species differ chiefly in coloration; the male genitalia are similar; the female genitalia are little known but we can characterize them as follows (examined in P. ammina DIAKONOFF,1983, P. mariepskopa sp.n.): Papilla analis moderate, short hairy; RAZOWSKI J.: Tortricidae (Lepidoptera) from South Africa 249 sterigma with short anteostial part and large postostial lateral arms; sclerite of antrum short, colliculum weak; ductus bursae slender, without cestum; signum may occur. A new character, a group of specialized scent scales near the apex of female hindwing, is found in Procrica. This is a synapomorphy with Archips, not found in other tortricines. Procrica intrepida DIAKONOFF, 1960 Material examined Ten male specimens from Transkei (Dwesa Forest), Durban, Charter's Kreek, late X, Natal) II. and V. 1955, Santa Lucia Bay, 30 IX, Natal; Dukuduku Forest in open grassland 28 V, Natal; Umdoni Park mid-XII; Illowo Beach I.; Port St. John's II. Remarks Described from Natal (Pinetown), South Africa; lectotype illustrated by CLARKE (1958); female lectoparatype not dissected. Type series in NHML. Genitalically similar to D. semilutea DIAKONOFF, 1960. Procrica pilgrima sp. n. (Fig. 20) Diagnosis Closely related and in male genitalia very similar to P. parva RAZOWSKI, 2002 from Kenya and mariepskopa sp. n. but pilgrima with dark brown hindwing and markings of forewing, and larger proximal part of uncus. Etymology The specific name refers to the type locality. Description Wingspan 16 mm. Head and collar brown, basal joint of labial palpus and frons brown orange; thorax yellow-brown, base of tegula with brown spot. Forewing not expanding terminally; costa strongly convex at base, termen straight to middle, not oblique. Ground colour yellow brown suffused with brown in terminal part of wing. Markings dark brown consisting of remnants of basal blotch at costa and dorsum; median fascia interruped subcostally, indistinct at middle; subapical blotch triangular. Cilia brownish, brown in costal half, tinged rust terminally. Hindwing dark brown; cilia paler, greyer. Male genitalia (Figs 7, 8). Uncus broad with proximal and posterior parts expanding medially; sacculus gently convex near middle; aedeagus rather short. 250 Polish Journal of Entomology 77 (3) Figs 1-10.
